Technora is a strong, tough and stretch-resistant material like a superhero costume that scientists made. It is made by taking a special kind of polymer (a bunch of tiny molecules stuck together) and spinning it out into long, thin fibers.
Technora looks a little like string but it's much stronger and can handle a lot more weight. It's used in all sorts of things like racing sails for boats, firefighter gear, and high-performance sports equipment.
Think of it like a really cool toy that can help people do amazing things without breaking or tearing. It's like having the powers of a superhero costume!
